This could be due to the ZIP INIT enabling some feature of the card that conflicts with your hardware. I'll elaborate below. > On the Zip card the switches are set as follows: > Switch bank 1 Switch bank 2 > #1 = on #1 = off > #2 = off #2 = off > #3 = on #3 = on > #4 = off #4 = on > #5 = off #5 = on > #6 = on #6 = off > #7 = off #7 = off > #8 = on #8 = off Quick documentation on the switches for the ZIP: SW1/1 = Cxxx/Dxxx cache disable. Leave this ON (cache enabled). SW1/2 = Joystick delay (OFF to enable delay). SW1/3 = AppleTalk delay (OFF to enable delay). This should be left ON. SW1/4 = Counter Delay (OFF to enable delay). This is only needed to allow the IIgs the pass self-test 05XXXXXX, and it will still fail a later test. SW1/5 = CPS Follow. This MUST be left OFF (enabled). SW1/6 = ZIP Disabled (OFF to disable acceleration). SW1/7 and 1/8 select the cache size: 1/7 1/8 ON ON 8k ON OFF 16k OFF ON 32k OFF OFF 64k SW2/1 through SW2/7 control the delay disable/enable for each slot: set the switch OFF to enable the corresponding delay. SW2/8 = Speaker Delay (OFF to enable delay). Your switch 1 settings look OK. Switch 2 is set to delay slots 1, 2, 6 and 7. All of these options can be changed by the ZIP INIT when you boot from your hard drive. The settings used by the INIT are controlled by the ZIPGS.Sys16 Utility. If you are only having problems after booting, I suggest that you remove the INIT from the hard drive, boot into GS/OS, reinstall the INIT, then use ZIPGS.Sys16 to set the options in the INIT to match those of the card before rebooting again. See if the problem persists. I suspect that setting slot 7 to FAST might be the cause of the problem. I can't be certain of this, as I've never used a ZIP with a RamFast. According to the manual, the RamFast has been tested and works with the ZIP. There is no mention of it requiring slot slowdown. You can also change all of the settings using the ZIPGS CDA or Control Panel. > I finally gave up and pulled my Zipcard out. Now everything works as > normal.

No software is needed - the ZIP will automatically behave according to its switch settings. The software allows you have a different set of acceleration settings when you boot from a particular GS/OS disk, and provides utilities for changing the settings on the fly. > I am hoping someone has gone through this before and can help me here.

There is no diagnostic function provided by the ZIP. -- David Empson dempson@actrix.gen.nz Snail mail: P.O. Box 27-103, Wellington, New Zealand
